Serial

Serial Port Pinout

On the WRV-54G board, the 9 pins look like:

              -----
(ttyS1 TX) 1 | 0 o | 2  +3.3V
           3 | o o | 4  +3.3V
           5 | o o | 6  GND
(ttyS1 RX) 7 | o o | 8  GND
           9 | o   |
              -----

(I've renumbered the pins to the standard pin convention for these connectors)

JTAG

J2 is definitely JTAG. It is using the 20-pin standard ARM JTAG pin layout.

Pin 1 on this header is on the edge of the board, closest to the LED.

Pinout: (from Intel)

                c[] LED5
       +3.3V -- 1 o o 2 -- NC
       nTRST -- 3 o o 4 -- GND
         TDI -- 5 o o 6 -- GND
         TMS -- 7 o o 8 -- GND
         TCK -- 9 o o 10 - GND
         GND - 11 o o 12 - GND
         TDO - 13 o o 14 - GND
      nRESET - 15 o o 16 - GND
          NC - 17 o o 18 - GND
          NC - 19 o o 20 - GND
